Repeating myself, does anyone render in passes?Do you do it in IRay (in case you do it with DAZ Studio)?

For those in the dark, rendering in passes is a technique where you render several different parts of your scene separately, and mount it all in a compositing software (like GIMP or Photoshop).You render the background, the foreground, the mid-ground, the characters, the props, all in different passes. It allows for more control of lighting and it reduces rendering time considerably. But it requires some skills and I haven't tried that yet.I would love to hear from someone who does it though.
